Oh boy, this launch looks so cool with the all the ice and snowy rocks in the background
For sure, the coolest launch setting there has been.

Does the flight termination system consist of the rocket free-falling into the ground resulting in a fiery explosion?
By just looking at the video, you can see that they cut the engines after the rocket starts tilting. I guess that’s the flight termination system. Also, it didn't fall into the ground, but into the water.

Ah yes very important distinction this

We had a clean liftoff, 30 seconds of flight and even got to validate our Flight Termination System. With this result, we feel confident to approach our second flight.” See: https://isaraerospace.com/newsroom-first-test-flight

Normally a flight termination system has explosive charges.

Gorgeous landscape.

Why does the first video just cut to nothing for the most exciting part, the fall?

#16I would love to invest in this.
Launching a rocket from Earth surface looks like such a complex challenge not completely solved, and companies consider a 30-seconds journey a great success.
I have sincerely no intention to trivialize this, but would we ever see rockets launched from Moon or low Earth orbit? It seems so inefficient to launch like how we do now.

there are lots and lots of proposals for doing this more cheaply. Most require megascale engineering, and would be a huge benefit to humanity if we could do it.
Some examples -- skyhooks -- large counterweighted swinging things that reach down into upper atmosphere and spin you right round baby right round -- a bunch of gravity assisted momentum ideas where you get the sun or the earth or what have you to get you really going, and then use that momentum to get a little thing up and moving more quickly. Space elevators -- hang a giant heavy thing out off one end, and drop a cable made of uninvented nanoscale tech down to earth, then just, you know, climb.
And then there's orbital construction, which requires some .. construction materials. The long standing idea has been to either go out to the asteroids and build there, or bring an asteroid or two here. Both have a lot of problems, and are a long way off. I think it's most likely that human governments will opt not to have the ability to make giant tungsten rods hanging over their countries, and will, to the extent moving an asteroid were ever viable, require they be a long way away, or alternately that we just go to the asteroids and construct elsewhere.
We are like maybe a century from all this being viable, and that's if companies like SpaceX keep moving at the clip they've been moving for that century.

Normally a flight termination system has explosive charges.
For larger rockets this is typical, however smaller rockets often only have a thrust termination system - for example apparently Rocketlab's Electron uses thrust termination.

The CEO said that it didn't blew up the pad: https://x.com/danielmetzler/status/1906307777242275881
I don't see why would you detonate the rocket if it doesn't pose danger to just fall down. Probably its also easier to collect the debris.
